The Panaracer Gravel King SK 650B Tire is ready to take on even the most hardcore roads. Featuring a more aggressive tread than the standard Gravel King tire, the SK utilizes Panaracer's ZSG Natural rubber compound for optimal natural puncture protection and grip. Go beyond the end of the road with confidence thanks to the 48mm-wide tread with raised knobs through the central patch, while more sizable blocky shoulder knobs keep you rubber-side down while cornering. The AX-α low rolling-resistance casing and anti-flat puncture protection breaker keeps the tires rolling even when the terrain gets rough. Take the comfort and durable protection to the next level with a tubeless setup, supporting inflation pressures of up to 60 PSI.
Folding aramid bead. Max inflation: 50 PSI (60 when tubeless). Claimed weight is 540 grams. Available in Black or Brown sidewall. Available in 700c sizes as well.
